Italian Keratin for Hair Extensions GVA keratin is manufactured in Italy specifically for hair extension bonding. The transparent grade melts at 180°C and the colored grades at 160°C, and that precise melting point is what produces smooth, uniform capsules instead of the lumpy or brittle bonds that cause most application problems. Sold in 20 g quantities in three shades. Why stylists choose it Keratin quality determines how a bond behaves for the next six months. This formulation does not stretch, run or crumble, sets quickly and holds a clean finish. It stays flexible during wear and resists the whitening that makes cheaper bonds visible over time.
